Same thing has happened to me a few times. To say its aggravating is an understatement. It'll say I'm in 1st going over the finish line with no sparrow in sight only to have the scoreboard pop up and say I somehow got beat by an invisible sparrow that was supposedly right next to me. WTF?! I feel your pain buddy. My best guess is it has to do with someone's bad connection or something along those lines.
